Operations before starting
■
Please read the instruction manual before using the machine. Pay special attention to the chapter on safety.
■
Only operators with the requisite competence and experience are allowed to operate the machine.
■
Always perform acomplete safety check before operating the machine. Please refer to the section on safety/safety checks/daily
maintenance.
■
Personal protective equipment must be worn.

Pay attention to the need for an ergonomic operator environment, and adjust the seat and steering wheel to suit your needs.
WARNING! Be careful when turning the seat so that you do not accidentally access the levers or
cause unintentional crane movement, which can lead to serious injury.
2.2 STARTING, STOPPING AND DRIVING INSTRUCTIONS, 850/850 H
Starting instructions
■
At temperatures lower than -20°C, utmost care should be taken into consideration and the machine must not be loaded with
more than half of its normally permitted loads.
■
The engine warm-up function should be used at temperatures between -10°C and +10°C. At temperatures below -10°C, run the machine
at idling speed for careful engine warm-up until it reaches atemperature to run the warm-up function, at which time the symbol will
light up. Instructions: Activate the engine warm-up programme symbol on the display. (1) Follow the instructions shown in the display.
Move the telescopic boom/crane tilt outwards to the end position and hold it there for about 5 seconds until the signal sounds. This
will cause oil overow to quickly heat up the hydraulic oil. Before the oil reaches an operating temperature of +15°C, the hydraulics
for the crane and transmission will be limited to protect the pumps. When the oil has reached the correct temperature, the engine
warm-up function will automatically stop the oil overow and the machine is ready to use. Never exceed the red marking on the
tachometer. It is automatically adjusted according to the operating temperature. (2)
■
Turn on the main power switch (please refer to safety/location of controls).
■
The manual throttle control should be in the start position, i.e. half throttle.
■
Switch o all external switches including the lights. Turn the ignition key to the glow position, and leave for 5-15 seconds depending
on the air temperature. Continue turning the key to START to start the engine.
■
Make sure the desired direction of travel has been set with the heading button (see the functional marking image)
■
Place your foot on the accelerator pedal. Press slowly to check that the correct travel direction is selected. If not, adjust. The direction
of travel is shown in the display.
Please note that the machine will not achieve full performance until it is fully warmed up. Thus, it can be perceived as being slower
and more sluggish at the beginning; this is perfectly normal.
